Embodiment 1

[0023] When in use, the stainless steel filter screen on the upper part of the oil filter housing is injection molded into one body with the oil filter housing; the oil filter insert protrudes from its own outer edge, and the inner side of the oil filter housing has a groove. The parts are interference-pressed into the ring groove inside the oil filter housing; the oil filter insert itself has a small hole to limit the amount of oil entering. The oil filter is installed at the inlet of the oil passage of the mechanical vacuum pump. The oil passes through the oil filter to be filtered out of impurities, and flows out from the small hole at the bottom of the oil filter to be throttled. The filter housing 5 is fitted together by the interference of the concave arc 9 on it and the convex arc 10 on the filter insert 6, and restricts the installation of the filter insert 6 into it through the bottom surface of the filter housing 5 depth. The oil can enter the oil filter 2 through t...

Embodiment 2

[0026] The filter insert forms an interference fit with the filter housing, one end of the filter insert is embedded in the filter cavity, and a small hole is provided on the filter insert, which communicates with the filter cavity . The depth of the filter insert into the filter housing is 1 / 2 of the height of the filter cavity to ensure that the oil can flow out smoothly. The inner wall of the filter housing is provided with a groove, and the outer wall of the filter insert is provided with a protrusion matching the groove, and the interference between the filter insert and the filter housing is formed by the cooperation of the groove and the protrusion Cooperate.

[0027] But the angle between the first oblique plane and the horizontal plane is 45 degrees, and the angle between the second oblique plane and the horizontal plane is 30 degrees. At the same time, when the ratio between the length of the first bevel and the length of the small hole, and the second bevel is 2:1...

Abstract

The invention relates to a machine oil filter. The machine oil filter is characterized in that the top of a housing of the filter is provided with a filter mesh, a filtering cavity is disposed in the housing of the filter, a filter insert and a housing of the filter form an interference fit, one end of the filter insert is inserted into the filtering cavity, the filter insert is provided with a small hole penetrating the filtering insert, and the small hole is communicated with the filtering cavity. When the machine oil filter is used, through the small hole disposed in the lower end of the machine oil filter insert, according to the small-hole flow principle and fits between the small hole and two diagonal planes, control of the oil incoming amount on a machine oil entering into a pump body of a vacuum pump is achieved, the fact that a too small hole needs to be machined in an oil path on a metal shell of the vacuum pump is prevented, and the machining difficulty of the vacuum pump is greatly simplified. The device integrates impurity filtering, oil incoming amount control and other functions into to one body, and greatly simplifies a lubricating system of the vacuum pump.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an engine oil filter used in automobile brake booster mechanical vacuum pumps. Background technique [0002] As the country's requirements for energy saving, emission reduction and driving safety of automobiles become more and more stringent, automobiles are often equipped with brake booster mechanical vacuum pumps that provide independent vacuum sources, which can suck the air out of the vacuum booster. When the driver steps on the brake pedal, the vacuum booster uses the difference between the vacuum inside it and the atmospheric pressure to amplify the force of the brake pedal in a certain proportion to push the hydraulic system so that the wheel brakes can control the braking of the vehicle, thereby improving the braking effect and enabling Stepping on the brake pedal saves effort, ensuring safe and rapid braking. [0003] Because the mechanical vacuum pump runs for a long t...
